Application files
Some virus scanners need to have list of permitted applications (exe). Following exe files are included to Renet software.
In the teacher computer:
ABCreate2.exe, Lame.exe, Quickmix.exe, ReAction2.exe, ReExam2003.exe, ReLan2.exe, ReMess.exe, ReUpdate.exe, Tcall.exe, Tec2003.exe, Trec.exe
In the student computer:
AudioTalk.exe, Esto2003.exe, Lame.exe, ReABC.exe, ReAction2.exe, ReAnalog.exe, ReCall2.exe, ReCmd.exe, ReKuva.exe, Rep.exe, RePhone.exe, ReRec.exe, ReUpdate.exe ReUser2.exe, ReWrite.exe, Java.exe
Sharing and Ports
Renet language studio needs network sharing only to Server computer where teaching material is stored and where student answers are saved. You do not need to do any network sharing to teacher’s or students’ computers. The server must have shared folders for material and answers. Folders can hold subfolders like “Sound” and “Text”.
Renet (ReLAN Pro v. 2.x) language studio uses following ports for UDP and TCP transmission:
Fixed ports:
4365, 4364, 4621, 4620, 5133, 5132, 5389, 5388, 3909, 3908, 4009, 4008, 3843, 3842, 4620, 4619, 3843, 3842, 3653, 3652, 8080
Changing ports:
4108 (4108-4363)
4109 (4109-4364)
5900 (5900-6156)
If there is only one Renet language studio in a network only the default port is used. If there is more than one Renet language studio in a network ReLANpro uses the first available port from the shown range. Besides the ports above, ReLANpro uses one UDP port for sound broadcasting, a program will find any free port.
